MC3000 single components

Short description

The system is delivered in single components and mounted in the tubing of a vehicle. As far as needed the single components are combined. For controlling there is a PLC available or the components can be integrated into an existing CAN Bus system of the vehicle, assisted by MicroCAFS technology support.

  • single components integrated into a vehicle system as far as needed as an individual solution
  • compressor is driven by a tooth belt via pto shaft or by hydraulic motor or optionally by second pto
  • precise positive pressure proportioning foam pump by exzentric worm pump, volumetric, no calibration needed
  • no flushing of foam pumps necessary after use
  • simple one button operation, every function can be switched by only pushing one button

In the standard configuration the foam dosing is done by two excentric worm pumps. Up to 4 pumps can be arranged optionally. The flow measuring is done by hightec magnetic inductive measurement. Independent of the type of the foam agent (viscosity) the accurate dosing will be made by the excentric worm pumps. Also the reliable dosing all over the working range is guaranteed under different working pressures.

CAFS is produced in the patented MicroCAFS mixing valve without remarkable pressure loss and without limitations of the water flow as well. Compressed air will be injected in the water/foam flow by proportional pressure regulation valve into the mixing valve. According to the quick reaction of the measurement and regulation, the unit can also handle quickly changing operating conditions (e.g. during chopping).

The unit allows CAFS flow rates up to minimum 800 l water per minute (about 1.200 l/min CAFS flow). This results in expanded CAFS flow of about 3.200 l/min. Therefore it also fits for using a monitor with about 1.200 l/min or several nozzle pipes at the same time. The unit provides high capacity for efficient and safe firefighting, also for indoor firefighting  and industrial firefighting.

Basic rules (tactical and technical) and sufficient self protection for attack teams have to be considered by fire fighting with CAFS as well. The attack teams must be trained regularly and constantly to enhance effectivity and safety for firefighting with CAFS.
